to be honest, they have lost a lot of their pop, and they aren't in very good condition. They could be skiid on the hill, but they wouldnt be very satisfactory. I 've been doing backyard jibbing and such with them, but they do still have intact edges. The edges are pretty rusty now though from lack of care and I dont have too much more faith in them. they'd be excellent for urban, but could still be skiid on a hill. I just feel wrong posting that they are in better shape than they are
